Could it be? Well yes it is sex.
Ever wonder how close you were to your fellow classamtes in highshcool sexually? Well if you were truly a whore(men included, as far as I'm concerned a whore is a whore or they could just be misunderstood) maybe you already know. But even if you only had few or even one relationship in highschool you might be surprized by how connected you were after reading about this study.
